Versatile fasciocutaneous flaps based on the medial septocutaneous vessels of the arm.

Abstract

Dissections in cadavers injected with latex confirm that direct septocutaneous branches from the brachial artery are the main source of irrigation for the fascial plexus of the inner arm. They are arranged in a vertical row from the level of the pectoralis major insertion down to a few centimeters above the medial epicondyle. Multiple fasciocutaneous flaps can be outlined utilizing these vessels, with either pedicled or island designs, proximally or distally based. Twelve clinical cases are reported. Axillary and elbow-crease contractures can be released with island flaps, and thumb and hand defects can be covered in a cross-arm fashion. Other clinical applications are suggested as well. The special quality of the skin transposed in this way, the simplicity of the surgical technique, and the circulatory reliability are the main advantages of these versatile flaps.
